Illumination Level Affects Unit Speed

I happened to notice that Abrams tanks with a hasty move order are moving along a road at about 10 km/h at night (0% illumination) but more like 40 km/h during the day. So far, I haven't seen any specific statement in the manual that unit speeds vary with light levels. Do speeds vary with the current illumination level percentage or with general time of day (day, dusk, night, dawn)?

Night driving speed is reduced for low illumination levels (less than 41%) unless the vehicle has night vision equipment for the driver. For example, some US recon HMMWV, some M113 APCs, some tanks (M48/M60/M551) have dedicated IR driving sights for the driver.

Something we will add to the Ops Guide if it's missing. Thanks for the information.

I remember this is a feature added in FCSS. And yes, units without IR driving will move at 25% of its max speed at 0% Illumination level

Seems like the Abrams added a passive IR system for the driver at some point, perhaps not in time for the FC:CW period.
